　Polishing machine is a commonly used power tool, polishing machine is composed of base, throwing disc, polishing fabric, polishing cover and cover and other basic components.
When the motor is fixed on the base, the cone sleeve used to fix the polishing disc is connected to the motor shaft by screws, the polishing fabric is fastened to the polishing disc through the ferrule, and the motor is connected to the power supply through the switch on the base to start, and the specimen can be polished by hand to apply pressure on the rotating polishing disc.
The polishing liquid added during the polishing process can flow into the square disc placed next to the polishing machine through the drain pipe in the plastic disc fixed to the base, and the polishing cover and cover can prevent ash and other debris from falling on the polishing fabric when the machine is not in use and affecting the use effect.
The polishing rate of the polishing machine is low to solve this contradiction is to divide the polishing into two stages, the purpose of rough polishing is to remove the polishing damage layer, this stage should have a large polishing rate of Z, the surface damage formed by the rough polishing is a secondary consideration, but it should also be as small as possible, followed by fine polishing (or final polishing), the purpose is to remove the surface damage caused by rough polishing, so that the polishing damage is reduced to Z small, when polishing the polishing machine, the specimen grinding surface and the polishing disk should be absolutely parallel and evenly pressed on the polishing disk, Care should be taken to prevent specimen flying out and new wear marks due to excessive pressure.
At the same time, the specimen should also be rotated and moved back and forth along the radius of the turntable to avoid local wear of the polishing fabric too fast In the polishing process, the micronized suspension should be continuously added, so that the polished fabric maintains a certain humidity, the humidity is too large to weaken the grinding mark effect of polishing, so that the hard phase in the sample presents embossing and non-metallic inclusions in steel and graphite phase in cast iron produces "tail dragging" phenomenon, the humidity is too small, due to frictional heat generation will make the specimen heat up, the lubrication effect is reduced, the grinding surface loses luster, and even black spots appear, and the light alloy will throw the surface.
In the process of removing paint, oxide layer, shallow marks and other operations, the polishing machine has become a very important product, and the production efficiency of the polishing machine can be better improved in the specific work process, and it is a very ideal equipment in many aspects of production.
From the aspect of equipment components, it can be understood that the base often becomes a very important part of the composition, whether the base is stable and whether the equipment can work very well has a very important impact, and from the polishing machine components can also be understood, throwing disc has also become a very important part, in the process of work The significance is also very prominent.
From the polishing machine components, we can know that the overall composition is very varied, among which the polishing fabric has also attracted the attention of friends.
